What is Ghost Spot?

Ghost Spot, also called Botrytis, is a type of fungal disease that affects many different types of plants, including vegetables, fruit trees, flowers, and ornamental plants. The disease gets its name from the pale blotches or “ghostly” spots that appear on the leaves and stems of affected plants.

How does Ghost Spot spread?

Ghost Spot is a highly contagious disease that spreads through spores that are released by infected plants. These spores can be carried by wind, water, or insects and can easily infect other plants in the area. Ghost Spot is most common in cool, damp weather conditions, which are ideal for fungal growth.

What are the symptoms of Ghost Spot?

The most obvious symptom of Ghost Spot is the appearance of white or greyish spots on the leaves and stems of infected plants. These spots may also be surrounded by a brown or yellow ring and will eventually cause the infected part of the plant to wilt and die. In fruit trees, Ghost Spot can cause fruit to rot or become discoloured, making it unsuitable for consumption.

How do you prevent and treat Ghost Spot?

Prevention is the best way to avoid Ghost Spot in your garden. Here are a few tips to keep your plants healthy:

  • Water your plants in the morning so that leaves have a chance to dry out during the day.
  • Remove infected plant debris as soon as possible, as spores can linger on dead plant material.
  • Space plants apart to increase air circulation and decrease humidity.
  • Apply a fungicide when necessary, following the manufacturer’s instructions carefully.

 

If you do notice Ghost Spot in your garden, it’s important to act quickly to avoid the disease spreading. Here are a few steps to take:

  • Remove and dispose of infected plant material.
  • Avoid watering infected plants from overhead.
  • Apply a fungicide to prevent further spread, being sure to follow the instructions carefully.
  • Consider pruning your plants to increase air flow and reduce humidity.
  • Ghost Spot is a common fungal disease that can affect a wide range of plants, but with careful attention and good gardening practices, it can be prevented and treated effectively.
